STMicroelectronics STLINK-V3PWR probe

The STLINK-V3 is designed to debug and program an STM32 microcontroller. The probe is designed to transfer data faster than the previous generation and with more flexibility, due to its STDC-14 connector and its support of a virtual COM port. Besides traditional programming and debugging, the probe can measure the power consumption of an STM32, draw energy profiles and help visualise current draws to help developers enhance their code.

The probe can sense currents from 100 nA to 50 mA, 300 nA to 150 mA, 600 nA to 300 mA and a 500 mA peak mode. It can also perform power measurements from 160 nW to 1.65 W with a 2% accuracy on the whole range to enable developers to target any microcontrollers, from the ultra-low-power ones to the highest-performing models.

Users can connect the power and ground of the STLINK-V3PWR probe to the correct pins on their development board and use the USB-C interface to send data to a PC. The probe also supports JTAG, SWD and VCOM, and provides bridge capabilities like UART, I2C, SPI or USB. Hence, teams prioritising power consumption can use the STLINK-V3PWR as their only probe. Additionally, it can supply the target STM32 board with up to 2 A and offer overcurrent protection through the USB-C cable, which can be useful when engineers are in the field and need to power their system.
